La machine de découper à fil chaud selon l'invention peut présenter les particularités suivantes :
- les points de fixation peuvent être des pivots déportés sur lequel le cadre est monté rotatif à l'intérieur du châssis ;
- le cadre peut être un cadre rectangle avec deux petits côtés parallèles entre lesquels est tendu un premier fil de coupe qui s'étend parallèlement au plan du châssis et deux grands côtés parallèles entre lesquels est tendu un second fil de coupe qui s'étend à travers le plan du châssis ;
- un mécanisme d'actionnement, par exemple à câbles et poulies, peut être prévu à l'intérieur du cadre pour déplacer lesdits premier et second fils de coupe selon deux directions de coupe orthogonales ;
